Check your local high schools for camps. My husband runs a half day camp for baseball twice a summer for about 75 per kiddo. Most of the other sports do too. Its a good way for them to get some interaction with lots of kids and they learn a lot. And the sport teams earn a good bit of cash for new uniforms/field improvements/ect.

We do summer daycamps. There are tons here. Community centre ones run about $25/day and the more interesting ones like bike camp/sailing camp etc.. are about $75/day. Last summer dd did 4 of the more interesting ones and some cheaper ones. I took a week off and DH took a week off.

When dd2 is older though and there are 2 of them I think I'll be looking for some other alternative for the summer. Maybe some kind of aupair/nanny.
